Introduction to IoT – Chapter 4 Quiz Answers

1. What term is used to describe the intelligence demonstrated by machines?

  • machine learning
  • natural intelligence
  • artificial intelligence
  • IBN

Explanation: Refer to curriculum topic: 4.1.2
Artificial Intelligence (AI) refers to systems that mimic cognitive functions such as learning and problem solving normally associated with humans. This is why AI is also defined as intelligence demonstrated by machines.

2. What is artificial intelligence?

  • the ability of a device to “learn” based on code and provided data
  • the intersection of innovation and society
  • the gathering of data from sensors
  • the connectivity of multiple devices and transmission of data through the internet

Explanation: Refer to curriculum topic: 1.1.1
Artificial intelligence is logic shown by electronic devices that are programed to learn and modify their own code based on parameters and data.

3. Which field has traditionally been tied to automation?

  • robotics
  • medicine
  • education
  • sports

Explanation: Refer to curriculum topic: 4.1.1
Automation was commonly associated with the manufacturing industry and tied to the field of robotics, but now automation is everywhere.

4. What are two characteristics of artificial intelligence? (Choose two.)

  • It translates intent into policies and then uses automation to deploy appropriate network configurations.
  • It uses intelligent agents that interact with the environment and make decisions to reach a specific goal.
  • It is an agile, responsive network technology that scales easily and adapts to meet business requirements.
  • Artificial intelligence uses statistical techniques to give computers the ability to learn from their environment.
  • It uses systems that mimic human cognitive functions such as learning and problem solving.

Explanation: Refer to curriculum topic: 4.1.2
Artificial Intelligence, also known as AI, is the intelligence demonstrated by machines. AI uses intelligent agents to perceive the environment and make decisions to accomplish a specific goal or objective. AI systems mimic cognitive functions normally associated with human minds such as learning and problem solving.

5. Which ML technology can be used to identify and track individual persons?

  • facial recognition
  • shape recognition
  • credit card fraud detection
  • e-readers

Explanation: Refer to curriculum topic: 4.1.2
Increased use of cameras has promoted facial recognition, which builds a pattern of specific facial features that is used to identify and track individuals.

6. Which element of the IBN model orchestrates policies and configures systems?

  • activation
  • assurance
  • translation
  • physical and virtual infrastructure

Explanation: Refer to curriculum topic: 4.1.0
The activation element of IBN occurs after the intent has been specified and the policies created. This enables individual devices to be provisioned to match intent-based policies.

7. What are two examples of automation? (Choose two.)

  • A robot cleans up an industrial chemical spill.
  • A building automatically adjusts the heating and lights based the routine of the occupants.
  • A user changes TV channels via a wireless remote.
  • A customer uses online banking to pay a bill.
  • An automobile is started remotely by the owner.

Explanation: Refer to curriculum topic: 4.1.1
Automation is any process that limits or eliminates the need for human intervention. In the examples given, a building that automatically adjusts lighting and heat and a robot cleaning up spills do not require human intervention.

8. Which action takes place in the assurance element of the IBN model?

  • configuring systems
  • translation of policies
  • verification and corrective action
  • integrity checks

Explanation: Refer to curriculum topic: 4.1.0
The assurance element of the IBN model is concerned with end-to-end verification of network-wide behavior.

9. What is a key feature of the translation element of the intent-based networking model?

  • application of business intent to network configuration
  • provisioning of intent-based policies
  • verification of configuration before devices are deployed
  • end-to-end verification of network-wide behavior

Explanation: Refer to curriculum topic: 4.1.3
There are three key elements of the intent-based networking model: assurance, translation, and activation. The translation element is concerned with the ability to apply business intent to network configuration.

10. Which technology enables features such as speech recognition, product recommendations, and credit card fraud detection?

  • machine learning
  • natural intelligence
  • artificial intelligence
  • IBN

Explanation: Refer to curriculum topic: 4.1.2
Machine learning gives computers the power to learn from the environment and then respond or act on certain conditions. Some practical uses of machine learning include malicious code detection, network intruder detection, optical character recognition, computer speech recognition, and computer vision.

11. True or False?
An appliance that lowers power consumption during peak demand is considered a smart device.

  • true
  • false

Explanation: Refer to curriculum topic: 4.1.1
Smart devices have the ability to alter behavior depending on the environment.

12. What is a requirement for a device to be referred to as a smart device?

  • The device stores data that is retrievable.
  • The device can accept human input.
  • The device can make a decision or take a course of action based on outside information.
  • The device can perform a series of steps based on programmed code.

Explanation: Refer to curriculum topic: 4.1.1
Smart devices have the ability to alter behavior depending on the environment.

13. Which technology uses AI and other technologies to reconfigure a network to comply with service levels?

  • JSON
  • ML
  • CSV
  • IBN

Explanation: Refer to curriculum topic: 4.1.3
Intent-based networking (IBN) uses artificial intelligence (AI) and machine learning (ML) to control the function of a network to accomplish a specific purpose. If a particular service level is not being met, the intent-based network can generate an alert, make suggestions, or automatically reconfigure the network.

14. What three technologies control network functions to accomplish a desired intent in an intent based network? (Choose three.)

  • machine learning
  • cloud computing
  • robots
  • advanced analytics
  • automation
  • artificial intelligence

Explanation: Refer to curriculum topic: 4.1.0
Intent-based networking leverages automation, artificial intelligence, and machine learning technologies to control network functions to accomplish a specific purpose, or intent.

15. Which two applications commonly use ML technology? (Choose two.)

  • credit card fraud detection
  • e-readers
  • graphic design
  • playground safety scanning
  • speech recognition

Explanation: Refer to curriculum topic: 4.1.2
Some of the more common uses of ML technology include product recommendation online, credit card fraud detection, and speech/shape/facial recognition.
